[Analysis and follow-up study on 8 children with combined congenital heart disease treated with simultaneous trans-catheter therapy].
OBJECTIVE
Interventional treatment for childhood combined congenital heart disease (CHD) has developed very quickly and more new types of occluders have emerged in recent years. The aim of this study is to investigate the efficiency and safety of interventional treatment for combined CHD in children.


METHODS
Eight children with combined CHD (4 boys and 4 girls), aged 6.1+/-2.9 years, underwent simultaneous transcatheter therapy. Of the 8 children with CHD, 1 case had atrial septal defect (ASD), ventricular septal defect (VSD) and patent ductus arteriosus (PDA), 1 case had ASD, PDA and pulmonary stenosis (PS), 1 case had ASD and PDA, 1 case had patent foramen ovale (PFO) and PS, and 4 cases had ASD and PS. The methods of transcatheter intervention for these patients were as follows: in patients with ASD,VSD and PDA, the occlusion of VSD was performed first, followed by PDA and ASD occlusions; in patients with ASD, PDA and PS, the occlusion of percutaneous balloon pulmonary valvuloplasty (PBPV) was performed first, followed by PDA and ASD occlusions; in patients with PFO and PS, the occlusion of PBPV was performed first, and PFO occlusion followed; in patients with ASD and PS, the occlusion of PBPV was performed first, and ASD occlusion followed.


RESULTS
The intervention operation was successfully performed in all of the 8 patients. No serious adverse events occurred during the operation. No residual shunt was found and all the occlusion devices were in the suitable sites shown by transthoracic echocardiography (TTE) and X-ray right after the operation. In the 6 patients with PS, the systolic pressure across the pulmonary valve decreased from 75.3+/-15.6 mmHg (before operation) to 14.0+/-5.6 mmHg after operation (P<0.05).A 3.4+/-1.2 years follow-up demonstrated that no residual shunt occurred and gradients across valve or coarctation sites were within the limit of satisfactory results. No complications were observed during the follow-up.


CONCLUSIONS
Transcatheter interventional therapy for childhood combined CHD can obtain satisfactory results by proper procedures.
